Application filed April 20, 1911.

Serial No. 622,261.

To all whom it may concern:

Be it known that I, Gnonon W. DUNHAM, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in Gas- TankHolders for Motor-Vehicles of which the following is a specification,reference being had therein to the accompanying drawmgs. y a

In the present state of the art it is usual to provide automobiles witha gas tank for compressed acetylene or other illuminating gas, and asthese tanks must be removed for re-charging they are detachably mountedupon the vehicle frame usually adjacent to the step or running board.

It is the object of the present invention to impart a more ornamentalappearance to this tank by providing a sheath or surrounding case whichmay be enameled or otherwise finished. As this sheath is not permanentlyattached to the tank, the latter may be removed when necessary forrecharging, and the sheath itself is notsubjected to injury as would bethe case were the tank itself to be enameled or finished.

In the drawings, Figure 1 is a perspective view of a portion of an antand running board showing ,the gas tank and sheath; Fig. 2 is a crosssection.

A is the frame of the vehicle, B is the running board and G are bracketssecured to the frame and adapted to receive the as tank D. This tank issecured in a brac et by suitable clamping means such as the screw clampsE.

obile frame.

F is the sheath or -ornamental casing for surrounding and sealing thetank D. This is preferablyformed of sheet metal enameled or otherwisefinished, bent into cylindrical form, but with its opposite edgeunconnected and preferabl overlapping. ThlS permits of clam ing t e tankin the supporting brackets C as the sheath is collapsible and willfreely conform to the shape of the tank and the bracket bearing.

Whenever the tanks are to be exchanged the clamps G are loosened, thetank and sheath attached and the sheath is then engaged with thesubstitute tank and again clamped in the brackets.

What I claim as my invention is:

The combination with a frame, of a gas tank, a bracket fixedly securedto said frame, said bracket having a clam ing portion for det-achablyholdin the tank, and an independently remova 1e metallic sheathsurrounding said tank and interposed between the latter and the bracket,said sheath in its applied position havin free adjacent end portions andbeing fiexi 1e to permit of con-' traction in its diameter, whereby thetank and sheath are secured by a clamping means common to both.

In testimon whereof I afiix my signature in presence 0 two witnesses.

GEO. W. DUNHAM.
